Can you ever really start over?

It's the question that follows Ariana now that she's reunited with the boys from the Sound of Us. Haunted by the past and her hopefully soon to be ex-husband, Ari is dragged along as the band continues its world tour.

Touring the world together...it's what they all used to dream about.

Sold out stadiums and screaming fans, it's everything anyone would want.

But with broken hearts to mend, groupies to ignore, and someone who clearly wants Ariana to leave for good, is their dream more of a nightmare?

Can Ariana discover her own song before it's too late?
